Abstract

The utility model relates to a valve core direct-opening water tap without leakage in a diaphragm cutting off type. The appearance structure is similar as a common water tap. The difference is that a water inlet chamber and a water outlet chamber in a valve body (1) and a cylinder chamber on the upper portion are arranged on the same axial line. A guide sleeve (6) is sheathed with a valve handle (3) to be assembled into the cylinder chamber. The end opening of the water outlet chamber is blocked by a sealing diaphragm (2) fixedly arranged on the front end surface of the valve handle (3). A fastening ring (5) spirally arranged on the end opening of the cylinder chamber tightly compresses the guide sleeve (6) to compress and seal the round edge of the sealing diaphragm on the round end surface of the water inlet chamber. The water entering into the valve body can not be discharged to the upper portion of the sealing diaphragm. The sealing diaphragm (2) can conduct the valve opening in a straight line type by only rotating a spiral handle (4) assembled on the valve handle (3) with a small angle. The rotary friction between the utility model and a water outlet does not exist and thus the service life is long.

Description

Valve core direct-opening leakless water tap

The utility model relates to a kind of barrier film cutting type water tap, and particularly a kind of spool heads straight for to open does not have the water tap of leakage.

Being seen in the market exhausted most water tap all is the structural type that adopts rotary spool to open and close, because the Sealing that installs on its spool is frequent and the water outlet sealing surface rotation extrusion friction of valve body, leaks so be damaged easily to cause.

The purpose of this utility model is to provide to the public that a kind of sealing film is not fragile, long service life, leak free new type water tap.

Utilize accompanying drawing below, so that clearly illustrate our inventive concept and specific embodiments:

Fig. 1 is a general structure schematic representation of the present utility model.

Technical measures of the present utility model is to make the spool of tap realize the straight line opening and closing. It is roughly similar to the contour structures of common tap: also include spool and swing handle (4) that valve body (1), diaphragm seal (2) and valve rod (3) form, the water inlet on the valve body (1) and the rectangular position of delivery port shape arrange. Difference is, the water chamber wall outer ring in the valve body (1) is intake antrum, the tube chamber, a garden that above water chamber and intake antrum, is being coaxially set, and the inner bottom surface in tube chamber, garden namely is the garden end face of intake antrum. The fairlead (6) and the valve rod (3) that are being set with valve rod (3) are fitted in the tube chamber, garden, be packed in diaphragm seal (2) on valve rod (3) front end face cuts down body (1) with the face shutoff water chamber port, on the garden end face of the limit, garden of diaphragm seal (2) by guide sleeve bottom face press seal intake antrum in valve body (1) body of (6), the projection that is arranging on valve rod (3) body sidewall is installed in the axial channel of offering on fairlead (6) inwall, use again the dead ring (5) of a spinning on the port of tube chamber, valve body (1) garden compressing the top end face of fairlead (6), both can place restrictions on fairlead (6) rotates in tube chamber, garden, can help again fairlead (6) with limit, the garden compacting of diaphragm seal (2) on the end face of the garden of intake antrum, make into water and can't leak into diaphragm seal (2) with the upper part, simultaneously valve rod (3) can only be moved up and down and can not Rotate. The upper end of valve rod (3) partly is thread segment, swing handle (4) is equipped with the thread segment of the inner bolt hole offered in its inner chamber and valve rod (3) upper-end part of driving, the tube chamber, garden that swing handle (4) the while enclosure valve body (1), the port of swing handle (4) is opened and is being made internal thread,, on the port of swing handle (4), just can avoid when using tap swing handle (4) is not intended to revolve taking off with a retaining ring (7) spinning. For guaranteeing sealing effectiveness, the used diaphragm seal (2) of the utility model is made and is the dried mushroom shape, and with the port of taper end face shutoff valve body (1) water chamber of diaphragm seal (2), diaphragm seal (2) is again the groove of pillow block on the front end face of the lip clamping valve rod that shrinks on the central blind hole port that is arranging with its inner face centre, be packed on the front end face of valve rod (3), use other securing member thereby save. On diaphragm seal (2) limit, garden, preferably also be provided with the water shutoff line of rabbet joint, this just can more effectively improve its sealing property.

Owing to adopt the said structure technical measures, swing handle (4) only needs very little angle of rotation, just spool can be mentioned or falls, thereby allow sealing (2) leave or shutoff valve body (1) water chamber end face, so this new type water tap is in use very just agile, its spool is only made up and down short distance traveling priority, and diaphragm seal (2) does not produce spin friction with valve body (1) water chamber end face, not fragile, so the long service life of this new type water tap; The current that enter valve body (1) are sealed film (2) end face bottom all, and leakage phenomenon will not take place the valve body swing handle.

Claims
